I keep reading about Dr. Lerner's Energy Index. I really can't figure out where I would fit in, because I don't really need naps, but my physical capacity is very small. http://www.treatmentcenterforcfs.com/energy_index_score/index.html If you look at the scale, I fit high on some levels, but very low on others. A few months ago I was at a 0 for sure. Now I have the mental capacity to read, watch TV without a problem, can talk on the phone, surf the web, all without getting too tired at all. I don't need naps and sleep 8 or 9 hours per night. But physically, I have such neurological problems, pain, and PEM, that I can only walk through the house a couple of times a day before the nerves in my legs go crazy, I can sit up, but need to have my feet up. As long as my feet are up, I can sit up for a few hours. I spend the majority of my time in bed, but spend half of that time sitting and half laying. I get up to get myself some food, but my arms barely work because they are so painful and weak and go numb. Standing upright is difficult because I have POTS and muscular chest pain that is pretty severe. I'm trying to track my progress, but Lerner's Energy Index isn't totally making sense for my case. What do you think?
